To explore dipeptides that interact with PPARα and influence lipid metabolism.
Used AlphaFold2 for predicting dipeptide binding to PPARα
Tested Ile-His, Phe-Ala, and Ala-Pro in HepG2 cells
Monitored cholesterol accumulation as an outcome measure
Ile-His and Phe-Ala significantly reduced cholesterol accumulation in HepG2 cells
Ala-Pro did not affect cholesterol levels
Study demonstrates the potential of structure-based prediction for identifying dipeptides affecting lipid metabolism

Resumen

Abstract The structural basis for dipeptides modulating PPARα remains unclear. AlphaFold2 identified Ile-His as a candidate predicted to interact with a novel alternative binding site. In HepG2 cells, Ile-His and Phe-Ala reduced cholesterol accumulation, whereas Ala-Pro had no effect. These findings support the utility of structure-based prediction as a hypothesis-generating approach for identifying dipeptides associated with PPARα-related modulation of lipid metabolism.
